Description

A kind of hot box double end Horizontal core shooter
Technical field
Field of the present invention relates to a kind of large table top (1 meter of x2 rice), the hot box shoot core machine of dijection head.
Background technology
Our factory provides high trade mark magnesium iron rotating disk and Rock Arms for famous robot building business ethics national treasury, world card (KUKA) company for a long time, owing to there is no large table top hot box shoot core machine; long 1.7 meters of Rock Arms core can only divide three sections; assemble use after production; production efficiency is low; quality can not ensure, manufacturing schedule can not meet customer requirement. the hot box shoot core machine of the large table top of production (1 meter of X2 rice) must be designed to meet Production requirement for this reason.
Summary of the invention
The invention provides a kind of hot box double end Horizontal core shooter, no matter far and near it has to penetrate chews but pressure unanimously ensures the core degree of packing everywhere; Penetrate air-flow in head steadily not disorderly; Penetrate head to penetrate sand, molding, get that core is synchronous, automaticity is high more.
A kind of hot box double end Horizontal core shooter, it comprises four root posts, column is installed with base, collar tie beam and top board from bottom to up successively, base is provided with workbench by linear bearing and guide pillar, workbench has closing cylinder and plunger tip oil cylinder, workbench is provided with mould underframe, is provided with lower core box in mould underframe, is provided with lower core ejecting device bottom lower core box; Collar tie beam has core box, and upper core box and lower core box upright position are on same straight line; Top board top is provided with sand hopper, gate part, compressed oil cylinder, blasting unit and penetrates sand air ducting system, and top board has left and right guide rail, sand cylinder, upper core ejecting device and sand cylinder mobile device; Described sand cylinder has penetrates head, and penetrate in head and have M type deflector, described sand hopper has two, is distributed horizontally to the both sides of compressed oil cylinder, is equipped with gate part and sand cylinder below corresponding each sand hopper.
The planar dimension of above-mentioned workbench is 1mX2m.
Above-mentionedly connect core machine establishing core pusher side face to be also provided with.
Above-mentioned sand cylinder mobile device comprises sand cylinder movable cylinder and roller, and roller moves on left and right track.
Above-mentioned blasting unit and upper core ejecting device control by compressed oil cylinder.
Above-mentioned core shooter also comprises PLC control system, and it realizes matched moulds, penetrates sand, plunger tip, suspended core and die sinking automation.
The present invention achieves following technique effect:
1, table top 1 meter of x 2 meters and at present on the market the work top of equivalent specifications only have 1 meter of x 1 meter, the blank (100Kg core shooter table top maximum on the market is at present less than 1.6 meters) of equivalent specifications large table top hot box shoot core machine filled up by this machine;
2, because work top greatly ensures that workbench operates steadily, workbench by 4 Φ 100 guide pillar and adopt linear bearing and centralized oil supply mode to move up and down, stable movement, freely, precision is high in activity;
3, several large technological process automaticity is high, due to have employed PLC technology from matched moulds, penetrate sand, plunger tip, suspended core, die sinking all achieve automation;
4, sand-shooting head and the design of upper plunger tip breach traditional spring reset and have employed Long Distances oil cylinder and make sand-shooting head and upper plunger tip stroke reach more than 270, provide possibility for plug-in type penetrates the design of chewing mould;
5, production efficiency is high, core quality is good, only need clean circulation timei of equipment 60 seconds (not containing firm time) 1.8 meters of long cores can be produced due to work top die, ward off exempt from former same specification core shooter due to structure limit and produce the core being greater than a meter and must assemble service efficiency by two pieces and improve 3-4 doubly, and significantly reduce labour intensity and improve casting accuracy and yield rate;
6, due to large scale mould can be used, sand cores of castings number of packages cylinder sand core structure can be reduced and improve casting quality;
7, traditional core shooter all only has one to penetrate head, comprise the core shooter of 100Kg, if run into large-sized mould may occur that to chew pressure inadequate from penetrating penetrating away from head, die cavity core penetrates unreal situation, in order to address this is that, we devise centre-to-centre spacing and are 870 two to penetrate head be that 1.7 meters of cores penetrate sand to length simultaneously, and this design place is short, and the core shooting time ensure that the core degree of packing everywhere;
8, penetrate in head and have employed M type deflector structure, penetrate in head at traditional core shooter, because only having one to penetrate head, all adopt ladder type deflector structure, and in dijection head core shooter, have two to penetrate head, ask that penetrating sand chews us deflector structure has been designed to M type to high pressure gas and sand mixed flow better be drawn, this design solves the order ground that injection sand such as chewing penetrated by long mould preferably.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
See Fig. 1-2, a kind of hot box double end Horizontal core shooter, it comprises four root posts 1, column is installed with base 2, collar tie beam 3 and top board 4 from bottom to up successively, base is provided with workbench 6 by linear bearing and guide pillar 5, and workbench has closing cylinder 7 and plunger tip oil cylinder 22, and workbench is provided with mould underframe 8, be provided with lower core box 9 in mould underframe, bottom lower core box, be provided with lower core ejecting device 10; Collar tie beam has core box 21, and upper core box and lower core box upright position are on same straight line; Top board top is provided with sand hopper 11, gate part 12, compressed oil cylinder 13, blasting unit 19 and penetrates sand air ducting system 14, and top board has left and right guide rail 15, sand cylinder 16, upper core ejecting device 17 and sand cylinder mobile device 18; Described sand cylinder has penetrates head, and penetrate in head and have M type deflector 24, described sand hopper has two, is distributed horizontally to the both sides of compressed oil cylinder, is equipped with gate part and sand cylinder below corresponding each sand hopper.Connect core machine 23 establishing core pusher side face to be also provided with.
